Flynn Roofing Co. was established in 1997 by Stephen Flynn. We are a small family-operated company that specializes in residential and commercial roofing, both asphalt shingles and rubber roofing. Some of our non-residential customers have included a nursing home, motel, town hall building, condo associations, a Mason lodge, and multiple office buildings. Our goal is to provide our customers with outstanding customer service and complete satisfaction. We pledge to return every phone call in a timely manner and address every question completely. We have an extensive listing of references showing our satisfied customers. We are not satisfied with your job until you are satisfied. We serve the Greater Boston area, the South Shore and Metro West. We are fully insured, including workers compensation and we use absolutely NO subcontractors, which is almost unheard of in this industry. The company you hire to do your job will be the company that arrives at your home. We pledge to install your roof as quickly as possible, while maintaining our strict quality standards. We work on one roof at a time and will be at your home daily (weather permitting) until your roof is completed. We work in an efficient and orderly manner, leaving your yard as we found it at the start of the job (some customers have said even better!). Flynn Roofing Co. is a Certainteed Select Shingle Roofer company, enabling us to offer our customers who choose Certainteed shingles a five-star warranty. This warranty includes a 15 or 20 year workmanship guarantee, along with the standard materials warranty. We purchase this warranty for ALL of our customers. We are also a GAF Authorized Installer. We are a proud member of the Northeast Roofing Contractors Association and the Better Business Bureau. We have had 0 complaints reported to the Better Business Bureau since we joined on 1/4/05.

"What I thought was going to be a painful process turned into a pleasant experience. Mr. Flynn was very timely in giving me a quote, supplying information about the materials, paperwork such as insurance certificate , and not subbing out the job. Mr. Flynn's crew was here at 7:50 AM. Stopped for lunch at 11:30 returned to work promptly at 12:30 and was finished with the job by 3. They were all very professional and courteous. The clean up was impeccable. Mr. Flynn and his crew know how to run a business. Kudos to Robyn too for all her help. Great Company!"

After 25 years of owning one of NH most trusted waterproofing companies my family moved back to MA 5 years ago. I opened a foundation repair business to continue doing what I enjoy and have years of experience. I will personally provide a free estimate for what is needed to repair issue and I'll be the person doing the repair. All work comes with a 10 year warranty. Whether you need a basic foundation crack repaired or you have a more serious issue we are able to do the repair. I am a certified Fortress Stabilization installer and use the finest products available. Remember I will be the the person doing the repair.

"Ed sealed a number of cracks in my basement walls. A couple were pretty awkward and had minor leaks afterwards but Ed promptly came back to resolve. Would definitely recommend and use again if necessary in the future."

"Joe and his team did a superb job of renovating my bathroom in a 1929 vintage building in Cambridge, MA. The final result is modern and highly functional while looking beautiful in an older building. Joe helped me pick materials and finishes that I would not have discovered on my own. He and his team were respectful of my home making sure that there was as little disruption as possible and wore masks and maintained distance at all times. When I miscommunicated with a house cleaner near the end of the project, Joe did much of the cleaning himself. Above and beyond. Last but not least, the work was finished on time. Amazing.

Structural Engineering questions, answered by experts

Yes, you can put a doorway in a structural wall; in fact, most exterior doors are set into structural walls. The project is a little more challenging than installing a door in a non-load-bearing wall because you need a structural engineer to assess the wall and make sure it’s safe to create a wall opening. Your engineer’s report will include instructions for your contractor on how and where to install additional supports, like steel headers above the door, to distribute the weight above to the wall on either side of the door.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.

The depth of any foundation style depends on your climate and how deep the frost line is, as building code requires that the footers of a foundation—which are built into a monolithic slab—sit at least a foot below the frost line. At the southern tip of Florida, for example, a monolithic slab foundation would only need to sit 12 inches under the soil at the widest parts. On some parts of the Canadian border, the frost line is 100 inches, which would mean a minimum of 112 inches, which is prohibitively deep for a monolithic slab.

Squeaky floors don’t always mean structural damage. Usually, it’s caused by friction somewhere inside your floor—whether it’s a loose floorboard or a gap between the subfloor and joists. If there is structural damage, you’ll notice other signs like soft or sagging floors, cracks that go from the wall to the ceiling, and horizontal cracks on your foundation.

Their expertise in identifying potential problems early and implementing durable solutions safeguards your home’s integrity.
